Optec Inc. 2-inch to SCT Thread Adapter: Precision and Versatility for Astronomical Equipment

 

  • Secure SCT Adapter: Designed to securely fit 2" x 24tpi SCT male telescope threads, enhancing connection stability for various astronomical accessories.
  • Exceptional Precision: Maintains tight tolerances of +/- 0.003 inches, providing a slip-fit that is highly reliable and effective.
  • TCF-S Focuser Compatibility: Perfectly matches the three thumbscrews on the TCF-S focuser's drawtube, with a precision-machined dovetail to eliminate flexure.
  • Rugged Construction: Features a heavy wall and standard SCT-thread, making it rugged yet user-friendly for connecting to a wide range of SCT accessories.
  • Wide Compatibility: Suitable for use with Celestron f/6.3 telecompressors, various filter wheels, and camera faceplates, among other SCT accessories.
  • Considerations for Certain Filter Wheels: Advises caution with some SCT female threaded filter wheels that may not accommodate the full 0.4" thread depth without obstruction.
  • Optional Retaining Ring: Optec provides an optional retaining ring for those needing to limit the in-travel of the male SCT threads.
  • Easy Rotational Alignment: Includes a machined brass registration screw for easy alignment with TCF-S focusers, simplifying re-insertion and rotational alignment.
  • Ideal Camera Nosepiece: Acts as an effective 2-inch camera nosepiece, facilitating easy and accurate alignment in low-light conditions.
  • Removable Brass Screw: The brass registration screw can be removed for compatibility with non-Optec focusers, enhancing the adapter's versatility.
